FIELD OF THE INVENTION

The present invention relates to a coupling device for a fire hosenozzle to enhance protection of life in fire situations, and morespecifically provides an expeditious and easy to use tool forfirefighters while fighting a fire.

BACKGROUND OF THE INVENTION

During the act of firefighting, firefighters commonly create a manmadeopening into a compartmentalized area containing a fire. This can posean extreme danger to both fire personnel and occupants who may bepresent in uninvolved areas. The responding firefighters are thereforefaced with the dilemma of rapidly getting water on the fire, whilemaintaining the integrity of the entrance door or other opening throughwhich they apply their hose streams. The solution, in the form of aquick connect stream applicator or rapid placement stream applicator, isa component and tool that assists firefighters in applying water tofires burning within an enclosed area, space or room in a building,structure or vessel, including a subway or utility vault. As such, thisdevice in all of its embodiments will be generally identified as RapidAccess Containment (RAC) devices. These RAC devices will allow thefirefighters to apply water to the fire without the need to create amanmade opening.

Firefighting is a dangerous activity stemming partly from theunpredictable nature of the fire in general and the difficulty in manycases for the fire fighter to access the fire. A common technique infirefighting is to limit or cut off a supply of oxygen so that a firecan be contained and extinguished. Various techniques exist toaccomplish this general goal, such as dousing a fire withoxygen-absorbing or limiting chemicals, or with water. When a fireoccurs in an internal structure, such as a residential apartment,warehouse, high-rise building or the like, it is difficult in manyinstances to access a fire area with firefighting equipment whilesimultaneously limiting or avoiding the introduction of oxygen to thefire environment. It should be noted that fire conditions aresignificantly exacerbated when doors or windows are left open or fail,especially on upper floors of hi-rise buildings, resulting in what iscommonly known as a “wind driven fire”. This phenomenon causes the fireto quickly reach blowtorch proportions in the public hallways andstairways and has claimed the lives of numerous firefighters andcivilians in recent years. Likewise, in the occurrence of an apartmentfire, for example, the sudden introduction of a large supply of oxygento a fire—which will occur when fire fighters open or force entry intoan apartment via its entrance door to gain access to the fire with firehoses—creating conditions for a phenomenon known as a “backdraft” whichhas threatened and taken the lives of many fire fighters over the years.

By definition, a backdraft is a phenomenon that can occur when an oxygendeficiency exists in a fire while the remaining combustible fuel gasesare present at a temperature hotter than the ignition point of the fuelgases. If oxygen is re-introduced to the fire, combustion will restart,often explosively, as the gases are heated by the combustion and expandrapidly because of the rapidly increasing temperature conditionoccurring.

Accordingly, it is an object of the disclosed embodiments to provide adevice that facilitates rapid access to a fire area by firefighters inorder to introduce water to the fire so that it can be contained andextinguished without the introduction of additional oxygen into the firearea and thus limit to the greatest degree possible the adverse effectsof any wind driven fire. At the same time the device will prohibit thespread of heat and fire gases into other occupied areas of the structureor building. As such, this device in all of its embodiments will begenerally identified as Rapid Access Containment (RAC) devices.

SUMMARY OF THE INVENTION

In accordance with a first embodiment, formidable entrance doors (i.e.,fire doors) providing access to an enclosed space within a building,structure or vessel will have a specialized device (a.k.a. a quickconnect stream applicator) or Rapid Access Containment Device (i.e. RACdevice-Door) built permanently into it for the purpose of directing astream of water onto the fire without opening the door or creatinganother access point in the initial stages of the fire. In this firstembodiment, the device can include a glass eyepiece viewer panel(peephole) for security purposes when installed in an entry door to aresidence. Finally, in the first and other embodiments, the device caninclude a locking, flush mount, watertight cap instead of a glass viewerwhen exposed to the elements, which can be easily opened by firepersonnel. In all of the embodiments described herein a tight seal isaccomplished at the point of connection between the nozzle and the quickconnect coupling. This is accomplished by means of a high heat resistantO-ring/seal made of a Perfluoroelastomer (FFKM) such as Kalrez, Markezor Chemraz This tight seal will facilitate ventilation of an involvedarea or space by attaching the nozzle and the uncharged length(s) ofhose to any of the device applications and to then attach the female endof the hose to a vacuum or external exhaust thereby minimizingunnecessary exposure to smoke, chemical agents and any other airbornepathogens by those present therein. Similarly, in extreme cases wherehostages are being held law enforcement can introduce a harmlesssedating agent into the building or space in an effort to neutralize anongoing threat posed by a hostage taker. These various access pointsinto a building or space may also be used to the advantage of lawenforcement to eavesdrop on conversations between the hostage taker andhis victims or possibly provide a view of the suspect.

In a second embodiment, the device can be installed within a metalfireproof box in a wall that separates the public hall stairway from aninterior hallway on any floor of a fireproof building (i.e. RACdevice-Stairway). This embodiment will assist in maintaining theintegrity of the public stairways under fire conditions, which arecommonly known as fire towers in high-rise office or residentialbuildings. It will assist in affording safe egress for both firefightersand civilians to the greatest degree possible when descending the publichall stairways on those occasions when a fire exists on a lower floor.It will give firefighters an opportunity to greatly limit the amount oftime that the door between the fire tower and the interior public hallon the fire floor is kept open thereby limiting the amount of heat andsmoke that enters the fire tower. This embodiment will increase thesurvivability of anyone who may have entered the fire tower on any floorabove the fire floor and yet afford firefighters the opportunity tocommence fire operations. This device will assist in the evacuation ofthe “attack stairway” (i.e. stairway wherein firefighters commence fireoperations, stretch and operate their hose lines) while fireextinguishment is underway. This is especially important since it isvirtually impossible for firefighters to ensure that the “attackstairway” is not chosen as a means of egress by people who may beseveral floors above the fire or may have already been overcome in thefire tower prior to their arrival.

A third embodiment is characterized in that the device can be installedin the roof with a threaded pipe extension and an attached streamdirector or distributor (i.e. RAC device-Roof). The purpose of thisdevice is to assist firefighters in getting water on the fire as quicklyas possible when the fire is burning in a concealed roof space commonlyknown as the cockloft (i.e. the space above the top floor ceiling andbelow the roof boards). A fire in this portion of a building createsenormous problems for firefighters since it often extends over severalapartments or commercial occupancies, involves a great deal ofcombustible material in the form of readily ignitable wood framing androofing material, and is extremely difficult to access for purposes ofwater application and extinguishment. Additionally, the task of cuttingholes in the roof or pulling sections of ceiling down on the top floorto determine the boundaries of a fire of this type is extremelydestructive, very time consuming, and difficult to accomplish. Theembodiments will provide the following advantages: When properly spacedand installed in the roof, the devices will serve as a ready means toidentify the boundaries of the fire while limiting the need for cuttingexamination holes in the roof. Once the direction of fire travel isdetermined and its boundaries identified, hose lines can be insertedinto the embodiments at the appropriate locations in lieu of the firedepartment's routine trench cut (i.e. a large rectangular cut in theroof made by firefighters). In essence, this system would amount to atrench cut with the added protection of an intact roof structure, ratherthan a dangerous condition that is often created when an actual trenchcut is made in the roof. Much time would be saved and property damagegreatly reduced since water application into the cockloft would bealmost immediate and in the specific area or section of the roof asrequired. This would prove most advantageous to stopping or greatlylimiting the spread of the advancing fire. Because the roof deviceopenings are relatively small (approximately 6 inches in diameter) thereis less likelihood of pulling the fire into uninvolved areas of thecockloft, as is the case when a trench cut or large roof opening is madein the roof by firefighters. Since the device openings also serve aslimited vent holes, the chances of a backdraft is reduced.

The disclosed devices allow the dissipation of heat and thus diminishthe expansion of steel I-beams from the heat of the fire, which willincrease the amount of time it takes for the collapse of the roofstructure or the subsequent ignition of adjacent wood structuralmembers. When a large fire occurs on an upper floor(s) of a high risestructure, people are often forced to seek refuge on the roof. This isespecially problematic when the fire is outside the reach ofconventional hose streams and people are precluded from descending thepublic hall stairs due to this lower floor fire. In such cases, if thedevice is installed in the roof of the high-rise, people can stretch thestandpipe hose line located on the top floor in the fire tower(s) intoone or more of these devices. This will increase their survival time onthe roof, limit the production of heat at roof level, and facilitate thelanding of a helicopter for rescue and removal of those trapped on theroof, when practical.

A fourth embodiment is characterized in that the device can be installedat street level above a subway platform or tunnel with a threaded pipeextension (i.e. RAC device-Subway). The purpose of this embodiment is tointroduce a hose stream from street level into an underground space suchas a subway in order to protect people that may be unable to evacuatedue to a fire, explosion or chemical release. This type of situationwill generally involve large numbers of people attempting to evacuatethrough limited emergency exits. This embodiment could also be used tointroduce a fresh air supply from street level into the subway areasimilar to that used in mining accidents. This is especially importantin recent years since there is an increased potential for terroristactivity with regard to explosives, anthrax, sarin gas and otherchemicals. The combination of fresh air and the application of waterstreams from street level could save many lives. This device willprovide a means by which lines of communication could be establishedfrom street level with those trapped in the subway and a means to obtainair samples, if necessary, in order to determine air quality andchemicals that may be present so first responders are adequatelyprotected in order to accomplish their objective. This embodiment alsofacilitates ventilation of the subway and permits the introduction ofsmall cameras to define the extent of the emergency.

A fifth embodiment is characterized in that the device can be installedin a wall or floor of a room, underground space, shaft or vessel (.e.RAC device-Confined Space). The purpose of this device is to introduce ahose stream from the exterior side of an enclosed room or space tocontain and extinguish a fire burning therein, while affording thosepresent in the structure, underground area, shaft or vessel anopportunity to reach safety. This type of situation will generallyinvolve large numbers of people attempting to evacuate through limitedemergency exits. This device could also be used to introduce a fresh airsupply into a room or confined space within a structure, undergroundspace, shaft or vessel. It is also a means by which air samples can beobtained, if necessary, to determine air quality and chemicals that maybe present within this space so first responders are adequatelyprotected to accomplish their objective. This device also facilitatesventilation of the involved area or space. This is possible since atight seal is accomplished at the point of connection between the nozzleand the quick connect coupling in all of the embodiments by attachingthe nozzle and the uncharged length(s) of hose to any of the deviceapplications and to then attach the female end of the hose to a vacuumor external exhaust thereby minimizing unnecessary exposure to smoke,chemical agents and any other airborne pathogens by those presenttherein. Similarly, in extreme cases where hostages are being held lawenforcement can introduce a harmless sedating agent into the building orspace in an effort to neutralize an ongoing threat posed by a hostagetaker. These various access points into a building or space may also beused to the advantage of law enforcement to eavesdrop on conversationsbetween the hostage taker and his victims or possibly provide a view ofthe suspect.

In general, the number of devices required would be a function of theoverall size of the enclosed area and the coverage being sought. Thedisclosed embodiments includes the following general characteristics: 1)quick connect/disconnect coupling permitting a fire hose nozzle to beconnected directly to the device wherever it might be installedfacilitating water application onto the fire; 2) a tilting mechanism sothat a water stream can be accurately directed, and, optionally, 3) aheat sensor to detect conditions in the fire area prior to gainingentry. It is noted that in fire districts or municipalities where thenozzle tip of choice is not the main stream tip as described herein, thequick connect coupling may be omitted. In the absence of the quickconnect coupling, any size hose nozzle can be inserted directly into therapid placement stream applicator as noted in FIGS. 1E, 3C, 4C, 5C and6C thus facilitating rapid water application onto the fire. The actualsize of the nozzle tip used will determine its movement within thedevice and angle of resultant water stream. A permanently affixed heavygauge, fire resistant rubber guide/stop is present within this rapidplacement housing leaving a center opening adequate in diameter toaccept fire nozzles up to three (3) inches in diameter so that a waterstream can be accurately directed in each of embodiments describedherein. The nozzle will rest on the high heat resistant rubberguide/stop and be in contact with it around its entire circumferencepermitting directional support, but in no way impede or hinder the quickremoval of the nozzle, if necessary.

DETAILED DESCRIPTION

FIGS. 1A, 1B, 1C and 1D generally show a quick connect device 100 inaccordance with an embodiment disposed in a door (i.e. RAC device-Door).The device 100 includes a housing containing side flange 102, an accesscover, such as an eyepiece and glass viewer panel 103 with viewing glass103B and viewing lens 103C and heat sensor 111 with an integral outsidethread inserted from the interior occupancy side of the door 101 througha preferred pre-drilled hole, preferably about four (4) inches indiameter and extending through to the opposite hallway side of the door.The hole is preferably located in the center of the door approximatelyfive (5) feet from the floor. It should be noted that the diameter ofthe hole and its height may be varied depending on the application andneed. However, the size of the hole is preferred to be four (4) inchesin diameter as to more easily accommodate a typical main stream nozzletip while still allowing the device to slightly rotate within thehousing as intended. The optional exterior decorative trim ring flange105 (preferably brass finish) containing inside thread 105 with attachedlaminate convex one way glass or convex mirrored viewer 106 is thensecured to the apartment side flange with outside thread 102 from anexternal side of the door, e.g., the hall side of the door, the hallside of the door by threading/turning clockwise, until it sits tightagainst the exterior of the door surface. This method of connectingexterior flange 105 to apartment side flange 102 will allow forinstallation of the device into doors with dimensions between 1 to 2inches in thickness. It is noted that the trim may be constructed of anydecorative metal such as nickel, stainless steel, chrome, or pewter withany finish desired, but brass is preferred in this embodiment based onboth durability and aesthetic appeal.

The eyepiece and glass viewer panel 103 with viewing glass 103B andviewing lens 103C permits a panoramic view of the public hallway frominside the apartment when the device is not being used as a firefightingtool. This eyepiece and glass viewer panel 103 with viewing glass 103Band viewing lens 103C fits centrally into inside/apartment side housingflange 102. The apartment side flange and housing contains an outsidethread that protrudes through and past the door outer surfaceapproximately one half inch. It is noted that the actual protrusiondepends on the thickness of the door or wall and the embodiment is notlimited by the door thickness or the amount of protrusion. That is, thedevice will generally fit doors that range in thickness from 1 to 2inches, but the application to door thicknesses may be varied to lessthan or greater than this range as desired. The protrusion readilypermits attachment of the outer threaded brass trim ring 105 andattached laminate one way convex glass or convex glass mirrored viewer106. It should be noted that the overall dimensions of this embodimentcan be modified for either or both functionality and or aesthetics.

To install the device 100, the user/firefighter/professional inserts theentire housing 102 constructed of a fire resistant metal alloy and allattached components therein, which include items 102, 103, 103A, 103B,103C, 104, 104A, 107, 108, 109, 110, 110C, 110D, 111, and 114 as shownin FIGS. 1A-1E, into the preferably four (4) inch opening from theapartment side to mate with exterior flange 105 as noted above. Aplurality of machine screws 112 are then inserted from the apartmentside of the door into the door trim ring 105 and are tightened securely.It should be noted that in other embodiments the screws may not extendinto the trim ring, but this is preferred to improve rigidity anddurability.

The operation of the device 100 will now be described in the event of afire. Upon breaking the laminate one way convex glass or convex mirroredglass 106 on the hallway side of the entrance door, the firefighterinserts the main stream nozzle tip 113 from a fire hose into the dooropening and pushes it against pivoting ball joint nozzle stop 104causing a slight (e.g., 0.5 inch) forward movement of the pivotingnozzle stop striking, ejecting and breaking the eye piece and glassviewer panel 103 and its components on the inside/apartment side of thedoor. The main stream nozzle tip collar 113A will pass locking pins,locking balls or locking rings 107 and lock nozzle 113 in place. Oncethe decision to start water is made, the nozzle will be opened and theback pressure from the operation of the hose stream will cause themovable nozzle connection body guide/stop 110 and attached high heatresistant rubber seal 110C with inner slide sleeve 110D to be physicallyforced backward off the outer surface of inward socket guide/stop 114permitting the forward nozzle stop bevel 104A to rest unimpeded on theinwardly rounded or slightly tapered edge of the inward socketguide/stop 114 allowing the connection to operate similar to that of aconventional ball and socket as seen in FIG. 1C. This movement permits arange of motion of the main stream tip and water stream to an angle of12 degrees with respect to a longitudinal axis of the nozzle in alldirections as the newly created connection is a pseudo ball and socketengagement. This angle, while relatively narrow at the door location,affords the firefighter substantial angular movement of the water streamwithin the room or occupancy on the opposite side of the door. It shouldbe noted that the range of motion, or angle, is disclosed asapproximately 12 degrees, but may be less than or greater than that asis desired. That is, a greater range of motion may be achieved bydirectly varying the size of the structure, individual components withinthe structure, and/or the attachment to or the means by which it isembedded in the specific embodiment herein disclosed.

During operation, the locking pins, locking balls or locking rings 107will engage behind the main stream tip collar 113A securing the mainstream-tip in place. Additionally, the spring release mechanism 108 withknurled locking collar is visible around the perimeter of the hole inthe door on the hallway side. Once a decision is made to remove the mainstream tip from the door and thus the quick connect stream applicator,the water supply is shut down. The firefighter will then depress thespring release mechanism 108 with knurled locking collar located on bothsides of the main stream nozzle tip 113 from the hallway side with thethumb and index finger of one hand and push the locking collar 108forward. This will permit the release of the locking pins, locking ballsor locking rings 107 from the main stream tip collar 113A and theretraction of the main stream nozzle tip 113 from the door using theother hand.

It should be noted that, prior to breaking the glass and inserting thenozzle, the protruding shape of the laminate one way convex glass orconvex mirrored glass viewer 106 on the hall side of the door permitsthe firefighter to simply slide his glove hand along the door when hisvision is obscured due to fire conditions to identify the specificlocation for main stream nozzle tip 113 insertion. That is, in a heavysmoke condition a firefighter would simply slide his hand to the rightof the laminate one way convex glass or convex mirrored glass viewer andfeel for the protruding heat sensor 111 to confirm the correctlocation/apartment of the fire for hose stream application. In addition,if included, the heat sensor 111 will extend approximately 1 inch andglow red when temperatures within the apartment reach in excess of 150degrees Fahrenheit or any other threshold temperature so desired. Thiswill further assist firefighters in identifying the particular apartmentwhere the fire is located.

FIG. 2 shows the particulars of the heat sensor. Heat sensor 111consists of an external metal housing 111A that is contained within theembodiment and an attached flange that will be seated on the surface ofthe hallway side of the door. Heat actuated center pin 111 B will extendfrom a heat sensor by an amount to provide a visual indication of a heatcondition, such as one inch and glow red when temperatures in excess of150 degrees, or any other set threshold temperature, is reached on theinterior side of the door. Expandable heating element 111C upon exposureto temperatures of 150 degrees or higher will push center pin 111Boutward as described above. Item 111D is located at the tip of metalhousing 111A and is constructed of a low melting metal alloy that whenexposed to temperatures of 150 degrees or any other desired higherthreshold temperature will melt thus permitting the expansion of heatingelement 111C and cause center pin 111B to pop out approximately one inchand glow red on the hallway side of the door. It is noted that thepop-out sensor length is not limited to one (1) inch and may be anylength that is desired.

FIG. 1E generally shows the rapid placement stream applicator device 100disposed in a door during use with a different construction as describedabove, namely, comprising a high heat resistant rubber guide/stop 110Binstead of locking pins, locking balls or locking rings 107. The deviceof FIG. 1E consists of a cylindrical metal waterway with an outsidethread constructed of a fire resistant metal alloy (i.e. stainlesssteel) and attached to an apartment side housing flange 102 alsocontaining eyepiece and glass viewer panel 103 with viewing glass 103Band viewing lens 103C and heat sensor 111. The housing side flange 102,with its components, is inserted from the apartment side of the door 101to be connected with exterior flange 105, through a preferredpre-drilled hole approximately 4 inches in diameter that is located inthe center of the door approximately 5 feet from the floor. It should benoted that diameter of the hole and its height may be varied dependingon the application and need. However, the size of the hole is preferredto be 4 inches as to accommodate a typical nozzle used by firefighterswhile permitting freedom of movement of such nozzle that the angle ofthe hose stream can be approximately 60 degrees above or below thehorizontal in a 360 degree radius thus permitting the hose stream to bedirected to the floor or ceiling within approximately 4 feet of the doorin which it is operated. High heat resistant heavy gauge rubberguide/stop 1106, approximately 3 inches in diameter is inserted into thewaterway and compressed against the apartment side flange 102 within thecavity of the door. This high heat resistant rubber guide/stop 1108 willcontain a center opening measuring approximately 2½ inches in diameter.The exterior decorative preferably brass trim ring 105 with attachedlaminate one way convex glass or convex glass mirrored viewer 106 isthen secured to the apartment side flange 102 from the hallway side ofthe door such as by threading, until it sits tight against the exteriorof the door surface and the high heat resistant rubber guide/stop 1108located within the internal waterway. It is noted that the trim may beconstructed of any decorative metal of any finish desired, but brass ispreferred in this embodiment.

The eyepiece and glass viewer panel 103 with viewing glass 1038 andviewing lens 103C permits a panoramic view of the public hallway frominside the apartment when the device is not being used as a firefightingtool. This eye piece and glass viewer panel 103 with viewing glass 1038and viewing lens 103C is held in place with (4) spring plungers 103Aequally spaced around the perimeter of the inside ring of the panel asseen in FIG. 1A. This eyepiece and glass viewer panel 103 with itscomponents fits centrally into apartment side housing flange 102. Theapartment side flange and internal housing contain an outside threadthat protrudes through and past the door outer surface approximately ½inch. It is noted that the actual protrusion depends on the thickness ofthe door or wall and the embodiment is not limited by the door thicknessor the amount of protrusion. That is, the device will generally fitdoors that range in thickness from 1 inch to 2 inches, but theapplication to door thicknesses may be varied to less than or greaterthan this range. The protrusion readily permits attachment of the outerthreaded brass trim ring 105 and attached laminate one way convex glassor convex glass mirrored viewer 106.

To install the device of FIG. 1E, the entire housing 102 is insertedinto the preferably 4 inch hole from the apartment side and connected toexterior flange 105 as noted above. Screws 112, or other fasteners, arethen inserted from the apartment side of the door into the door trimring 105 and are tightened securely. It should be noted that in otherembodiments the screws may not extend into the trim ring, but ispreferred to improve rigidity.

The operation of this embodiment will now be briefly described. Uponbreaking this laminate one way convex glass or convex mirrored glassviewer 106 on the hallway side of the entrance door, the firefighterinserts the nozzle tip 113 into the door opening and pushes it throughthe center opening of the high heat resistant rubber guide/stop 110Blocated around the inside perimeter of the waterway resulting in thenozzle tip striking, ejecting and breaking the eye piece and glassviewer panel 103 with viewing glass 103B and viewing lens 103C on theinside/apartment side of the door. The nozzle will rest on the rubberguide and be in contact with it around its entire circumferencepermitting directional support, but in no way impede or hinder the quickremoval of the nozzle, if necessary. Once the decision to start water ismade, the nozzle will be opened and the stream directed to the limitsdescribed above. Once a decision is made to remove the nozzle, the watersupply is shut down. The firefighter will simply retract the nozzlepulling it backward through the high heat resistant rubber guide/stop110B. As in the above embodiment, it should be noted that, prior tobreaking the glass and nozzle insertion, the protruding shape of thelaminate one way convex glass or convex mirrored glass viewer 106 on thehall side of the door permits the firefighter to simply slide his glovehand along the door when his vision is obscured due to fire conditionsto identify the specific location for nozzle tip 113 insertion. Theheavy gauge high heat resistant rubber guide/stop 110B may be usedinstead of locking pins, locking balls or locking rings 107 to providean accurate and durable fit/engagement with the nozzle 113.

FIGS. 3A, 3B and 3C generally show device 227 disposed in a fire proofmetal box, referred to herein as the second embodiment or stairwayevacuation assist box embodiment (i.e. RAC device-Stairway). Thisembodiment consists of a preferred 12 inch by 18 inch by 6 inchrectangular metal fireproof box 221 into which a smaller metal box 222is inserted and nested. These two metal box halves are then joinedtogether at their sides with ½ inch machine screws 222B within a cinderblock wall opening. It should be noted that the overall dimensions ofthis embodiment can be modified for either or both functionality and oraesthetics. During installation of the stairway device, metal hallwaybox 222 is inserted into the larger metal stairway box 221 and as theboxes slide directly into one another and overlap they can be adjustedto fit into walls with dimensions from 6 to 10 inches in thicknessbefore being attached together with screws 222B. Furthermore the overalldimensions can be reconfigured to fit larger dimension walls. These twointerlocking sections contain 2 inch long permanently affixed rims 221Aand 222A on all four sides of their outer edges that rest up against theblock wall on both sides of the wall to insure anchorage. There is ahinged cover 225 affixed to the front of the metal box (i.e. thestairway side), which has a hinge 228 and can be readily opened with a1620 key; a key required to be carried by firefighters at all times. Thekey is inserted into keyway 223 within this hinged front cover 225. Arear cover 220 located on the back side (i.e. the hallway side) also hasa hinge 226 and is removable from within the metal box enclosure fromthe stairway side via an interior quick release latch 223A. Both hingedcovers 220 and 225 are hinged to their respective fireproof boxes 222and 221 at their lower edges permitting each of these covers to swingdownward toward the floor when opened. A securing bracket 224 adjacentthe hallway side supports the quick connect stream applicator 227constructed of a fire resistant metal alloy and all attached componentstherein, which include items 202, 204, 204A, 207, 208, 209, 210, 210C,210D, 211, 214 and 224 as shown in FIG. 3B.

The quick connect stream applicator device 227 and its surroundingconstruction is similar to device 100 described above. The quick connectstream applicator permits the nozzle of a fire hose to be quicklyattached and detached. This securing bracket 224 is connected directlyto the interior sides of the smaller metal box 222. Attached to bottomedge of securing bracket 224 is a fireproof blanket 224B ofapproximately 12×12 inches in size made of materials such as: siliconerubber glass fiber based cloth, ceramic fiber cloth, or Nomex Kevlarcloth. This fireproof blanket will have (2) approximately three-inchvertical cuts 224C spaced at four-inch intervals on the bottom edge ofthe blanket making for a better seal when fires hoses are insertedthrough the stairway box on the rollers. Fireproof blanket 224B willblock smoke and heated fire gases that are present in the hallway frominfiltrating into the stairway. The quick connect stream applicatorassembly 227 will accept the main stream tip that is attached to thecontrol nozzle (as seen in and previously disclosed in the firstembodiment above and FIG. 1A, item 113) and permits free movement of thecontrol nozzle handle 113D from the water full off position to the waterfull on position after being attached to the quick connect streamapplicator within the box.

Upon access to the box via the stairway side cover, heat sensor 211 willbe visible within the evacuation assist box and will release (i.e. popout) for heat conditions preferably in excess of 150 degrees Fahrenheitor any other threshold temperature so desired is reached on the interiorhall side of this box. That is, the heat sensor operates in a mannersimilar to that of the first embodiment described above. Also presentwithin the lower portion of this metal box 222 as seen in FIGS. 3A and3C is a metal hose roller 229, which is preferably 2 inches in diameterand the approximate width of the metal box. Metal hose roller 229 isdivided into (3) approximately four-inch sections 229B capable ofrotating independently of each other on the internal roller shaft givingfirefighters the ability to use multiple hose lines to extinguish thefire.

The operation of device 227 in the stairway evacuation assist box willnow briefly be described during use. First, firefighters will confirm orverify that there is a fire in a building equipped with fireproofdoor(s) separating the fire tower or public hall stairway from theinterior public hallway and that there is a possibility of eitherfirefighters or civilians being present on the stairway above the firefloor. Depending on heat conditions in the area of the stairwayevacuation assist box, firefighters will recognize the floor level ofthe fire by means of the heat sensor contained therein as described inthe first embodiment above. In addition and if possible, thefirefighters will next assess the amount of smoke and heat presentwithin the interior hall by quickly opening this fireproof door and thenclosing it to limit the amount of smoke and heat entering the stairwayto the greatest degree possible.

Once it is confirmed that there is a significant amount of heat andsmoke within the interior hall that is likely to hamper the safe egressof the occupants descending the public hall stairs, the first arrivingengine company will open the front hinged cover 225 on the metal box byinserting a 1620 key into the keyway 223 of the locking mechanism. Fromthe stairway side, they will then release the rear hinged cover 220 onthe metal box 222 with the quick release latch 223A located on theinside top portion of the box and cover, insert the main stream nozzletip 113 (that is attached to the controlling nozzle 113C) into the quickconnect stream applicator 227 causing it to move forward and to thenreturn to its original position.

Once the decision to start water is made, the control handle on thenozzle will be opened and the back pressure from the operation of thehose stream will cause the movable connection body nozzle guide/stop 210and attached high heat resistant rubber seal 210C with the inner slidesleeve 210D as seen in FIG. 3B to be physically forced backward off theouter surface of inward socket guide/stop 214 permitting the forwardnozzle stop bevel 204A to rest unimpeded on the inwardly rounded orslightly tapered edge of the inward socket guide/stop 214 allowing theconnection to operate similar to that of a conventional ball and socket.During operation, the locking pins, locking balls or locking rings 207will engage behind the main stream nozzle tip collar 113A (not shown inFIG. 3B) securing the main stream-tip in place. Additionally, the springrelease mechanism with knurled locking collar 208 is visible around theperimeter of the quick connect inner assembly. That is, the hose nozzleto quick connect stream applicator connection and operation is the sameas that described in the first embodiment and as seen in FIG. 1B. Alsoidentical to the first embodiment, the nozzle connection to the quickconnection stream applicator allows the connection to operate similar tothat of a conventional ball and socket with the entire structureallowing for movement of 12 degrees in all directions. The nozzle willthen be opened discharging water directly into the interior hall toextinguish fire in the immediate vicinity. After extinguishing the firein the hallway and the decision has been made to bring the hose lineinto said hallway to either extinguish the remaining fire therein or toadvance the hose line toward the main fire area. The water supply canthen be shut down and the main stream nozzle tip 113 can then be removedfrom the quick connect stream applicator. The firefighter will thendepress the spring release mechanism 208 with knurled locking collarlocated on both sides of the main stream nozzle tip 113 from thestairway side with his thumb and index finger of one hand and push thelocking collar 208 forward. This will permit the release of the lockingpins, locking balls or locking rings 207 from the main stream nozzle tipcollar 113A and the removal of the main stream nozzle tip 113 from thestairway metal box using the other hand. The hose line can then beretracted and passed over hose roller 229 located in the lower part ofthis stairway evacuation assist box. Firefighters can then quickly enterthe interior hall via the door separating the fire tower or public hallstairway from the interior hall and close said door behind them therebylimiting the amount of smoke and heat from entering into the publicstairway.. This is especially critical in cases of wind driven firesthat are known to create blowtorch type heat conditions in the hallways.Once in the interior hallway, firefighters can then retrieve and operatethe hose line that was passed through the stairway evacuation assist boxmoving toward the seat of the fire.

The hose roller 229 will provide a mechanical advantage to firefighterswho are pulling the hose through the stairway evacuation assist box. Asecond hose line can then be passed over the same hose roller 229 with(3) independent rotating sections 229B facilitating the stretching of asecond hose line, if needed, while maintaining the door separating thefire tower/stairway from the interior hall in a closed position untilassured that no one is present on the stairway whose safety would becompromised.

FIG. 3D generally shows device 227 in a fire proof metal box of thesecond embodiment with a different construction comprising a high heatresistant rubber guide/stop instead of locking pins, locking balls orlocking rings. This embodiment consists of a preferred 12 inch by 18inch by 6 inch rectangular metal fireproof box 221 into which a smallermetal box 222 is inserted and nested. These two metal box halves arethen joined together at their sides with ½ inch machine screws 222Bwithin a cinder block wall opening. During installation of the stairwaydevice, metal hallway box 222 is inserted into the larger metal stairwaybox 221 and as the boxes slide directly into one another and overlapthey can be adjusted to fit into walls with dimensions from 6 to 10inches in thickness before being attached together with screws 222B.Furthermore the overall dimensions can be reconfigured to fit largerdimension walls. These two interlocking sections contain 2 inchpermanently affixed rims 221A and 222A on all four sides of their outeredges that rest up against the block wall on both sides of the wall toinsure anchorage. There is a hinged cover 225 affixed to the front ofthe metal box (i.e. the stairway side), which is hinged 228 that can bereadily opened with a 1620 key. The key is inserted into keyway 223within this hinged front cover 225. A rear cover 220 located on the backside (i.e. the hallway side) is also hinged 226 and removable fromwithin the metal box enclosure from the stairway side via an interiorquick release latch 223A. Both hinged covers 220 and 225 are hinged totheir respective fireproof boxes 222 and 221 at their lower edgespermitting each of these covers to swing downward toward the floor whenopened. Securing bracket 224 located adjacent to the hallway sidesupports suspended rapid placement assembly 210A constructed of a fireresistant metal alloy with attached high heat resistant rubberguide/stop 210B contained therein as shown in FIG. 3B. The internalhousing assembly and associated nozzle guide/stop permits the nozzle ofa fire hose to be quickly inserted and readily removed. This securingbracket 224 is connected directly to the interior sides of the smallermetal box 222.

Internal rapid placement housing assembly 210A will accept the nozzle ona typical fire hose and permits free movement of the nozzle controlhandle from the full off to the full on position while being operatedwithin the box. Upon access to the box via the stairway side cover, heatsensor 211 will be visible within the evacuation assist box and willrelease (i.e. pop out) for heat conditions preferably in excess of 150degrees or any other threshold temperature so desired is reached on theinterior hall side of this box. That is, the heat sensor operates in amanner similar to that of the first embodiment described above. Alsopresent within the lower portion of this metal box 222 is a metal hoseroller 229, which is preferably 2 inches in diameter and divided intothree independent rotating sections 229B and spans the approximate widthof the metal box.

The operation of the modified device 227 in the stairway evacuationassist box will now briefly be described. First, firefighters willconfirm or verify that there is a fire in a building equipped withfireproof door(s) separating the fire tower/public stairway from theinterior public hallway and that there is a possibility of eitherfirefighters or civilians being present on the stairway above the firefloor. If possible and optionally, the firefighters will next assess theamount of smoke and heat present within the interior hall by quicklyopening this fireproof door and then closing it to limit the amount ofsmoke and heat entering the stairway to the greatest degree possible.

Once it is confirmed that there is a significant amount of heat andsmoke within the interior hall that is likely to hamper the safe egressof the occupants descending the public hall stairs, the first arrivingengine company will open the front hinged cover 225 on the metalevacuation assist box by inserting a 1620 key into the keyway 223 of thelocking mechanism. It should be noted that the use of the evacuationassist box is especially critical in cases of “wind driven fires” sincefires of this type have been known to reach blowtorch proportions in thepublic hallway. From the stairway side, they will then release the rearhinged cover 220 on the metal box 222 with the quick release latch 223Alocated on the inside top portion of the box and cover, insert thenozzle tip 113 through the center opening of the high heat resistantrubber guide/stop 2106, which is compressed within the rapid placementinternal housing assembly 210A and located around the interiorcircumference of this opening. The nozzle will rest on the high heatresistant rubber guide/stop and be in contact with it around its entirecircumference permitting directional support, but in no way impede orhinder the quick removal of the nozzle, if necessary.

Once the decision to start water is made, the nozzle will be opened andthe stream directed to a maximum angle of approximately 60 degrees aboveor below the horizontal in a 360 degree radius thus permitting the hosestream to hit either the floor or ceiling within approximately 4 feet ofthe access box in which it is operated. Once a decision is made toremove the nozzle, the water supply is shut down. The firefighter willsimply retract the nozzle pulling it backward through the rubber guide.Once the hose line is shut down it can then be passed over hose roller229 located in the lower part of this metal box and firefighters canthen quickly enter the interior hall via the door separating the firetower from the interior hall and close said door behind them limitingthe amount of smoke and heat in the public hall stairway, and thenretrieve and operate the hose line that was passed through the metal boxmoving toward the seat of the fire.

The hose roller 229 will provide a mechanical advantage to firefighterswho are pulling the hose through the stairway evacuation assist box. Asecond or third hose line can then be passed over an adjacent hoseroller section 229B facilitating the stretching of the second or thirdhose line, if needed, while maintaining the door separating the firetower from the interior hall in a closed position until assured that noone is present on the stairway whose safety would be compromised.

Firefighters engaged in firefighting operations when entering or exitingthe fire floor in buildings equipped with this type of device shall, tothe greatest degree possible, maintain the door separating the firetower from interior hall in a closed position to ensure the safety ofthose present or likely to enter the attack stairway above the firefloor. This is especially critical in cases of a “wind driven fire” asdescribed above.

FIGS. 4A and 4B generally show the device 100 disposed in a roofaccording to a third embodiment (i.e. RAC device-Roof). The installationof this third embodiment will now briefly be described. An approximate 6inch hole is drilled in the roof between roof joists. Cylindrical metalhousing waterway 336 measuring preferably 6 inches in diameter with anattached preferable 2 inch roof flange 336A containing a fixed quickconnect stream applicator constructed of a fire resistant metal alloy327 and all attached components therein, which include items 302, 304,304A, 307, 308, 309, 310, 310C, 311, 314, 324 and 337 as shown in FIG.4B. This cylindrical metal housing 336 is inserted into the roof openinguntil roof flange 336A is seated firmly on the roof surface. Securingbracket 324 is an integral part of the cylindrical metal housing 336 andis the means by which the quick connect stream applicator 327 ispermanently attached to the inner walls of housing 336. The lowerportion of the securing bracket 324 contains an inside pipe thread 335measuring preferably 2 inches in diameter that accepts threaded stempipe extension 340 of variable lengths (e.g. depending on the depth ofthe space between the roof and the top floor ceiling) to which metalstream director 541 as shown in FIG. 6B is affixed by means of a malethread at its end that permits connection into the lower portion of stempipe extension 340. Stream director 541 will contain a number oforifices (e.g., 9 orifices) that permit stream disbursement at anapproximate 360-degree angle within the cockloft (i.e. space below theroof boards and above the top floor ceiling). In lieu of stream director541 as described above, a distributor 342 containing a similar malethread at its end can be screwed directly into the lower portion of stempipe extension 340. This will permit the distributor to operaterotatably, mechanically and fluidly while allowing water to enter thepipe extension 340 and to exit the distributor 342 while it is spinningthus resulting in a uniform distribution of water in this concealedspace. It should be noted that the overall dimensions of this embodimentcan be modified for either or both functionality and or aesthetics.

Installation of this third embodiment further includes drilling ⅛ inchholes from the roof side through roof boards at the predrilled holes336B located around the perimeter of roof flange 336A. Next, 4 one wayscrews of ¼ inch by 2¼ inch with retaining rubber washers are insertedthrough predrilled holes 336B in roof flange 336A and tightened untilthe flange is seated properly on the roof surface. Finally, a preferablylime green cover 336C having threads on its outer perimeter is screwedinto roof flange 336A having corresponding mating threads on its innersurface along with attached high heat resistant O-ring 336E until thecover is tight and flush with the roof flange. This roof cover 336C willbe flush with the roof flange 336A, water tight and finished with a limegreen reflective type color to facilitate ready identification underfire conditions as seen in FIG. 4B. It is noted that other cover colorsand methods of applying the color and finishes such as electroplating,immersion plating, ceramic coatings, chemical coatings and metalliccoatings applied to the cover are within the scope of the embodiment,but a green colored cover is preferred because it is easily visible.This metal cover will contain a keyway 337 and two parallel indentedslots 336D approximately two (2) inches apart on its top surface as seenin FIG. 4B.

In use, the firefighter will simply insert a 1620 key (typically carriedby firefighters) into a keyway 337, turn the key counter clockwise ¼turn and unlock cover 336C. Once the cover is unlocked the firefighterwould then insert the fork end of a Halligan tool (also typicallycarried by firefighters) or similar tool into indented slots 336D on thesurface of the lime green cover 336C and turn counter clockwise toremove the cover. Next, the main stream tip 313 is inserted into openingin the roof against pivoting ball joint nozzle stop 304. It is notedthat this will result in a ½ inch downward movement of the main streamtip 313. At the same time, the main stream tip collar 313A will passlocking pins, locking balls or locking rings 307 and lock the nozzle inplace. The spring release mechanism 308 with knurled locking collar isvisible around the perimeter of the cylindrical metal housing 336. Next,the nozzle control handle will be opened and the back pressure from theoperation of the hose stream will cause the movable connection bodynozzle guide/stop 310 and attached high heat resistant rubber seal 310Cto be physically forced backward off the outer surface of inward socketguide/stop 314 permitting the forward nozzle stop bevel 304A to restunimpeded on the inwardly rounded or slightly tapered edge of the inwardsocket guide/stop 314 allowing the connection to operate similar to thatof a conventional ball and socket (all similar to the first and secondembodiments as described above).

During operation, the locking pins, locking balls or locking rings 307will engage behind the main stream tip collar 313A securing the mainstream-tip in place. Additionally, the spring release mechanism 308 withknurled locking collar is visible around the perimeter of the quickconnect inner assembly. Unlike in the previous two embodiments, stempipe 340 is fixedly attached via securing bracket 324 and covers thewater exposing end of the quick connect stream assembly. The stem pipe340 has a metal stream director 541 as shown in FIG. 6B attached theretothat will contain nine orifices that will permit stream disbursement atan approximate 360-degree angle within the cockloft. In lieu of theabove stream director, a rotatably attached distributor 342 with aplurality of smaller distributing holes is provided to maximize waterapplication. Distributor 342 is also in fluid communication with thestem pipe 340 allowing water to enter and further rotate the distributor342. The net effect is a plurality of smaller, but high pressure streamsof water disbursed within the attacked area in a rotating fashion.

Once a decision is made to remove the main stream tip 313 from thecylindrical metal housing in the roof, the water supply is shut down.Subsequently, the firefighter will depress the spring release mechanism308 with knurled locking collar located on both sides of the main streamtip 313 with his thumb and index finger of one hand and push the lockingcollar 308 forward. This will permit the release of the locking pins,locking balls or locking rings 307 from the main stream tip collar 313Aand the retraction of the main stream nozzle tip 313 from thecylindrical metal housing with the other hand.

It should be noted that for maximum effectiveness, stream director 541as shown in FIG. 6B has to extend beneath the roof joists. Since thecombined length of the waterway and attached stem pipe 340 is a functionof the space between the underside of the roof boards and the top floorceiling it is expected that their combined length may be in excess of 3feet. Similar to the first and second embodiments and as previouslynoted, the nozzle connection to the quick connect stream applicatorallows the connection to operate similar to that of a conventional balland socket with the entire structure allowing for movement of up to 12degrees in all directions. Since the nozzle is moveable in thisembodiment to 12 degrees above and below the horizontal in alldirections the direction of this solid water stream within the largerattached stem pipe 340 will have a notable advantage, which will permitthis solid stream to be more accurately directed toward the angularholes in the stream director 541 and thus afford greater reach andcontrol of the stream direction being sought. In those instances when adistributor 342 is used in lieu of stream director 541 the waterpressure will cause the distributor to spin or rotate about the stempipe extension 340 and the additional angular moment, will result in apowerful spinning hose stream that is disbursed in a circumference ofapproximately 25 feet within the space below the roof boards and abovethe top floor ceiling.

FIG. 4C generally shows the rapid placement stream applicator disposedin a roof according to the third embodiment with a differentconstruction comprising a high heat resistant rubber guide/stop insteadof locking pins, locking balls or locking rings 307. The installation ofthis variation of the third embodiment will briefly be described. Anapproximate 6 inch hole is drilled in the roof between roof joists.Waterway 336 measuring approximately 2 inches in diameter with anattached preferable 2 inch roof flange 336A constructed of a fireresistant metal alloy and all attached components therein, which includeitems 310A, 310B, and 324 as shown in FIG. 4C is inserted into the roofopening until roof flange 336A is seated firmly on the roof surface. Thelower portion of waterway 336 contains an inside pipe thread 335measuring preferably 2 inches in diameter that accepts a threaded stempipe extension 340 of variable lengths (e.g. depending on the depth ofthe space between the roof and the top floor ceiling) to which metalstream director 541 as shown in FIG. 6B is affixed such as, for example,by means of a male thread at its end that permits connection into thelower portion of stem pipe extension 340. Stream director 541 willcontain nine orifices that will permit stream disbursement at anapproximate 360 degree angle within the cockloft (i.e. space below theroof boards and above the top floor ceiling). In lieu of stream director541 as described above a distributor 342 containing a similar malethread at its end can be screwed directly into the lower portion of stempipe extension 340. This will permit the distributor to operaterotatably, mechanically and fluidly while allowing water to enter thepipe extension 340 and to exit the distributor 342 while it is spinningresulting in an approximate 360 degree stream disbursement within thisconcealed space.

The installation of this variation of the third embodiment will alsoinclude drilling ⅛ inch holes from roof side through roof boards at thepredrilled holes 336B located around the perimeter of roof flange 336A.Next, 4 one way screws of ¼ inch by 2¼ inch with retaining rubberwashers are inserted through predrilled holes 336B in roof flange 336Aand tightened until the flange is seated properly on the roof surface.Finally, a lime green cover 336C having threads on its outer perimeteris screwed into roof flange 336A having corresponding mating threads onits inner surface along with attached O-ring 336E until the cover istight and flush with the roof flange. This roof cover 336C will be flushwith the roof flange 336A, water tight and finished with a lime greenreflective type color to facilitate ready identification under fireconditions as seen in FIG. 4B. It is noted that other cover colors andmethods of applying the color and finishes to the cover are within thescope of the embodiment, but a green color cover is preferred because itis readily visible. This metal cover 336C will contain a keyway 337 andtwo parallel indented slots 336D approximately two (2) inches apart onits top surface as seen in FIG. 4B.

In use, the firefighter will simply insert a 1620 key (typically carriedby firefighters) into a keyway 337, turn it counter clockwise ¼ turn andunlock the cover. Once the cover is unlocked the firefighter will theninsert the fork end of a Halligan tool (typically carried byfirefighters) or similar tool into indented slots 336D on the surface ofthe lime green roof cover 336C and turn counter clockwise to removecover. Next, the nozzle 313 is inserted into the cylindrical metalhousing 336 and through the center opening of high heat resistant rubbernozzle guide/stop 310B, which is compressed within internal housingassembly 336 and located around the interior circumference of thisopening. The nozzle will rest on the high heat resistant rubberguide/stop 310B and be in contact with it around its entirecircumference permitting directional support, but in no way impede orhinder the quick removal of the nozzle.

To remove the nozzle, the water supply is shut down and the nozzlesimply retracted by pulling it backward through the high heat resistantrubber guide/stop 310B. Unlike in the previous discussed embodiments 1and 2, stem pipe 340 is fixedly attached via waterway 336. Stem pipe 340has a metal stream director 541 as shown in FIG. 6B attached theretothat will contain nine orifices that will permit stream disbursement atan approximate 360 degree angle within the cockloft. In lieu of theabove stream director a rotatably attached distributor 342 withplurality of smaller distributing holes to maximize water applicationcan be used. Distributor 342 is also in fluid communication with thestem pipe 340 allowing water to enter and further rotate the distributor342. The net effect of this is a plurality of smaller, but high pressurestreams of water disbursed within the concealed roof space in a rotatingfashion. Once a decision is made to remove the nozzle 313 from thewaterway housing in the roof, the water supply is shut down and nozzlesimply withdrawn.

It should be noted that for maximum effectiveness, stream director 541as shown in FIG. 6B or distributor 342 has to extend beneath the roofjoists. Since the combined length of the waterway and attached stem pipe340 is a function of the space between the underside of the roof boardsand the top floor ceiling it is expected that their combined length maybe in excess of 3 feet. Therefore the reach and direction of the waterstream within the cockloft by this means will rest solely on the nozzlepressure and the size and shape of the orifices in either the streamdirector 541 or distributor 342, and not the position of the nozzle atroof level.

In those instances when a distributor 342 is used in lieu of streamdirector 541 the water pressure will cause the distributor to spin orrotate about the pipe extension 340 resulting in the disbursement of apowerful spinning hose stream in a circumference of approximately 25feet within the space below the roof boards and above the top floorceiling.

FIGS. 5A and 5B generally show a configuration for a sidewalk or streetfor a subway or tunnel application according to the fourth embodiment(i.e. RAC device-Subway). The installation of this fourth embodimentwill now be described. An approximate 6 inch hole is drilled in thesidewalk or street above either a subway or tunnel. Cylindrical metalhousing 436 measuring six (6) inches in diameter with an attached two(2) inch flange 436A containing a fixed quick connect stream applicator427 constructed of a fire resistant metal alloy and all attachedcomponents therein, which include items 402, 404, 404A, 407, 408, 409,410, 410C, 411, 414, 424 and 437 as shown in FIG. 5B. This cylindricalmetal housing 436 is inserted into the sidewalk or street opening untilthe flange 436A is seated firmly on the sidewalk or street surface.Securing bracket 424 adjacent the street side is an integral part of thecylindrical metal housing 436 and is the means by which the quickconnect stream applicator 427 is permanently attached to its innerwalls. The lower portion of the securing bracket 424 contains an insidepipe thread 435 measuring approximately 2 inches in diameter thataccepts a threaded stem pipe extension 440 of variable lengths (e.g.depending on the depth of the space between the sidewalk or street andthe underside of subway or tunnel ceiling). Depending on the angle ofstream penetration being sought, this stem pipe extension may containoptional metal stream director 541 as shown in FIG. 6B to facilitatemaximum stream disbursement within the subway or tunnel. Theinstallation of this fourth embodiment also includes drilling ¼ inch by2¼ inch deep holes (e.g., 4 holes) from street side into the sidewalk orstreet at the predrilled holes 436B located around the perimeter of theflange 436A using the flange as a template. Next, the entire cylindricalmetal housing is removed with the attached flange. Lead concrete shieldsor anchors are then inserted into the previously drilled holes. Thecylindrical metal housing is then reinstalled lining up the holes in theflange with the lead concrete shields and then ¼ inch by 2¼ inch one wayscrews or bolts with rubber retaining washers are inserted throughpredrilled holes 436B in flange 436A and the screws tightened until theflange is seated properly on the sidewalk or street. Finally, a limegreen cover 436C having threads on its outer perimeter is screwed intosidewalk flange 436A having corresponding mating threads on its innersurface along with attached high heat resistant ) O-ring 436E which isplaced into the flange 436A. This cover will be flush with the flange,water tight and finished with a lime green reflective type color tofacilitate ready identification under fire conditions.

Once again it is noted that other cover colors and methods of applyingthe color and finishes to the cover are within the scope of theembodiment, but a green color cover is preferred because it is readilyvisible. This metal cover will contain a keyway 437 and two parallelindented slots 436D approximately 2 inches apart on its top surface asseen in FIG. 5B. It should be noted that the overall dimensions of thisembodiment can be modified for either or both functionality and oraesthetics.

A brief description of the operation of this fourth embodiment will nowbe provided. In use, firefighters will simply insert the appropriatesubway emergency key that they carry into this keyway, turn it counterclockwise ¼ turn and unlock the cover. Once this cover is unlocked thefirefighter will then insert the fork end of a Halligan tool (alsotypically carried) or similar tool into indented slots 436D on thesurface of the lime green cover 436C and turn counter clockwise andremove the cover. Next, they will insert the main stream tip 413 intothe opening in the street against pivoting ball joint nozzle stop 404.It should be noted that this will result in a ½ inch downward movementof the main stream tip 413. At the same time, the main stream tip collar413A will pass locking pins, locking balls or locking rings 407 and lockthe nozzle in place.

Once the decision to start water is made, the controlling handle 113D onthe controlling nozzle 113C will be opened and the back pressure fromthe operation of the hose stream will cause the movable connection bodynozzle guide/stop 410 and attached high heat resistant rubber seal 410Cto be physically forced backward off the outer surface of inward socketguide/stop 414 permitting the forward nozzle stop bevel 404A to restunimpeded on the inwardly rounded or slightly tapered edge of the inwardsocket guide/stop 414 allowing the connection to operate similar to thatof a conventional ball and socket. During operation, the locking pins,locking balls or locking rings 407 will engage behind the main streamtip collar 413A securing the main stream-tip in place. Additionally, thespring release mechanism with knurled locking collar 408 is visiblearound the perimeter of the quick connect inner assembly. Like theprevious third embodiment, stem pipe 440 is fixedly attached to thesecuring bracket 424 and covers the water exposing end of the quickconnect assembly.

The stem pipe 440 has the capability of accepting optional metal streamdirector 541 as shown in FIG. 6B at its lower end, which is affixedthereto by means of a male thread and is equipped with nine orificesthat will permit stream disbursement at an approximate 360 degree anglewithin the subway or tunnel. This stem pipe extension may be of variablediameters and lengths and may or may not contain optional streamdirector 541. In either case the available stem pipe opening or streamdirector openings will be sufficient to maintain a fresh air supply, airquality assessment and permit ventilation of the involved area. Sincethe nozzle is moveable in this embodiment to twelve (12) degrees aboveand below the horizontal in all directions the direction of this solidwater stream within the larger attached stem pipe 440 will have anotable advantage, which will permit this solid stream to be moreaccurately directed toward the angular holes in the stream director 541and thus afford greater reach and control of the stream direction beingsought.

To remove the main stream tip 413 from the cylindrical metal housing inthe street, the water supply will be shut down. The firefighter willthen depress spring release mechanism with knurled locking collar 408located on both sides of the main stream tip 413 with the thumb andindex finger of one hand and push the locking collar 408 forward. Thiswill permit the release of the locking pins, locking balls or lockingrings 407 from the main stream tip collar 413A and the retraction of themain stream tip 413 from the cylindrical metal housing with the otherhand.

If fire conditions are not apparent when sidewalk cover 436C is removedand prior to hose nozzle connection, an opening approximately two (2)inches in diameter will exist. This opening will permit: 1) theestablishment of voice communications with those who may be trapped orincapacitated in the subway or tunnel below, 2) afford first respondersthe means by which they can obtain air samples in order to detect andidentify the presence of chemical or biological agents therein and, 3)to provide a means by which first responders can introduce a fresh airsupply into the subway station or tunnel, for the benefit of thoseindividuals who may be trapped or incapacitated below and in need offresh air. This device also facilitates ventilation of the involved areaor space. This is possible in all of the embodiments since a tight sealis accomplished at the point of connection between the main streamnozzle tip 413 and the quick connect coupling's high heat resistantrubber seal 410C. With the main stream nozzle tip 413 attached to thecontrolling nozzle 113C as seen in FIG. 2C and inserted into the quickconnect coupling in any of the device applications ventilation can beachieved. This is accomplished by attaching the female end of thepre-connected hose to a vacuum or external exhaust thereby minimizingunnecessary exposure to smoke, chemical agents and any other airbornepathogens.

FIG. 5C generally shows a configuration for a sidewalk or street for asubway or tunnel application according to the fourth embodiment with adifferent construction comprising a high heat resistant rubberguide/stop instead of locking pins, locking balls or locking rings. Theinstallation of the variation of this fourth embodiment will now bedescribed. An approximate 6 inch hole is drilled in the sidewalk orstreet above either a subway or tunnel. Cylindrical metal housing 436measuring 6 inches in diameter with an attached 2 inch flange 436Aconstructed of a fire resistant metal alloy and all attached componentstherein, which include items 402, 410A, 410B, 424, and 440 as shown inFIG. 5C. This cylindrical metal housing 436 is inserted into thesidewalk or street opening until the flange 436A is seated firmly on thesidewalk or street surface. Securing bracket 424 adjacent the streetside is an integral part of the cylindrical metal housing 436. The lowerportion of the securing bracket 424 contains an inside pipe thread 435measuring approximately 2 inches in diameter that accepts a threadedstem pipe extension 440 of variable lengths (e.g. depending on the depthof the space between the sidewalk or street and the underside of subwayor tunnel ceiling). Depending on the angle of stream penetration beingsought, this stem pipe extension may contain optional metal streamdirector 541 as shown in FIG. 6B to facilitate maximum streamdisbursement within the subway or tunnel.

The installation of the variation of this fourth embodiment alsoincludes drilling ¼ inch by 2¼ inch deep holes from street side into thesidewalk or street at the predrilled holes 436B located around theperimeter of the flange 436A using the flange as a template. Next, theentire cylindrical metal housing is removed with attached flange. Leadconcrete shields or anchors are then inserted into the previouslydrilled holes. The cylindrical metal housing is then reinstalled liningup the holes in the flange with the lead concrete shields and then ¼inch by 2¼ inch one way screws or bolts with rubber retaining washersattached are inserted through predrilled holes 436B in flange 436A andthe screws tightened until the flange is seated properly on the sidewalkor street. Finally, a lime green cover 436C having threads on its outerperimeter is screwed into sidewalk flange 436A having correspondingmating threads on its inner surface along with attached high heatresistant O-ring 436E is placed into the flange 436A. This cover will beflush with the flange, water tight and finished with a lime greenreflective type color to facilitate ready identification under fireconditions.

Once again it is noted that other cover colors and methods of applyingthe color and finishes to the cover are within the scope of theembodiment, but a green color cover is preferred because it is readilyvisible. This metal cover will contain a keyway 437 and two parallelindented slots 436D approximately 2 inches apart on its top surface asseen in FIG. 5B.

A brief description of the operation of this variation of the fourthembodiment will now be provided. In use, firefighters will simply insertthe appropriate subway emergency key that they carry into this keyway,turn it counter clockwise ¼ turn and unlock the cover. Once the cover isunlocked firefighters will then insert the fork end of a Halligan tool(also typically carried) or similar tool into indented slots 436D on thesurface of the lime green cover 436C and turn counter clockwise andremove the cover. Next, they will insert the main stream tip 413 intothe cylindrical metal housing 436 and through the center opening of highheat resistant rubber nozzle guide/stop 410B, which is compressed withininternal housing assembly 436 and located around the interiorcircumference of this opening. The nozzle will rest on the high heatresistant rubber guide/stop 410B and be in contact with it around itsentire circumference permitting directional support, but in no wayimpede or hinder the quick removal of the nozzle.

To remove the nozzle, the water supply is shut down. The firefighterwill simply retract the nozzle pulling it backward through the high heatresistant rubber guide/stop 410B. Like the previous third embodiment,stem pipe 440 is fixedly attached to the securing bracket 424. The stempipe 440 has the capability of accepting optional metal stream director541 as shown in FIG. 6B at its lower end, which is affixed thereto bymeans of a male thread and is equipped with nine orifices that willpermit stream disbursement at an approximate 360 degree angle within thesubway or tunnel. This stem pipe extension may be of variable diametersand lengths and may or may not contain optional stream director 541. Ineither case the available stem pipe opening or stream director openingswill be sufficient to maintain a fresh air supply, air qualityassessment and permit ventilation of the involved area. Since the nozzleis moveable in this embodiment in all directions the direction of thissolid water stream within the larger attached stem pipe 440 will have anotable advantage, which will permit this solid stream to be moreaccurately directed toward the angular holes in the stream director 541and thus afford greater reach and control of the stream direction beingsought.

If fire conditions are not apparent when sidewalk cover 436C is removedand prior to hose nozzle insertion, an opening approximately 2 inches indiameter will exist. This opening will permit: 1) the establishment ofvoice communications with those trapped or incapacitated in the subwayor tunnel below, 2) the means by which first responders can obtain airsamples in order to detect and identify the presence of chemical orbiological agents therein and, 3) to provide a means by which firstresponders can introduce a fresh air supply into the subway station or,tunnel to the benefit of those individuals who may be trapped orincapacitated below and in need of fresh air.

Figures 6A and 6B generally show a configuration for a wall or floor ofa room or vessel according to the fifth embodiment (i.e. RACdevice-Confined Space). The installation of this fifth embodiment willnow be briefly described. A 6 inch hole is drilled in the wall or floorfor the purpose of installation. Cylindrical metal housing 536 measuring6 inches in diameter with an attached 2 inch flange 536A containing afixed quick connect stream applicator 527 constructed of a fireresistant metal alloy and all attached components therein, which includeitems 502, 504, 504A, 507, 508, 509, 510, 510C, 511, 514, 524 and 537 asshown in FIG. 6B. This cylindrical metal housing 536 is inserted intothe wall or floor until the flange 536A is seated firmly on the wall orfloor surface. Securing bracket 524 adjacent the outside wall is anintegral part of the cylindrical metal housing 536 and is the means bywhich the quick connect stream applicator 527 is permanently attached toits inner walls. The lower portion of the securing bracket 524 containsan inside pipe thread 535 measuring approximately 2 inches in diameterthat accepts a threaded stem pipe extension 540 of variable lengths(e.g. depending on the depth of the wall or floor of the room or spaceto be protected). The lower portion of stem pipe extension 540 willcontain an inside thread that will accept a compact, optional, metalstream director 541, which will contain a male thread at its end thatpermits attachment into the lower portion of stem pipe extension 540.Stream director 541 will contain nine orifices. The center orifice ofthe stream shaper will be in line with stem pipe extension 540 while theadditional orifices will permit stream disbursement at an approximate360 degree angle, respectively. It should be noted that the overalldimensions of this embodiment can be modified for either or bothfunctionality and or aesthetics.

The installation of this fifth embodiment also includes drilling ¼ inchby 2¼ inch deep holes into the wall or floor from the exterior side atthe predrilled holes 536B located around the perimeter of the flange536A using the flange as a template. The entire cylindrical metalhousing with attached flange is then removed and lead concrete shieldsor anchors are inserted into the previously drilled holes. It is notedthat other types of wall anchors can be used to attach the flange to thewall, but shields or anchors are preferred. Next, the cylindrical metalhousing is reinstalled lining up the predrilled holes in the flange withthe lead concrete shields and then ¼ inch by 2¼ inch one way screws withrubber retaining washers are inserted through predrilled holes 536B inflange 536A and the screws tightened until the flange is seated properlyon the wall or floor surface. Finally, a lime green cover 536C havingthreads on its outer perimeter is screwed into flange 536A havingcorresponding mating threads on its inner surface along with attachedhigh heat resistant O-ring 536E is placed into the flange 536A. Thiscover will be flush with the flange and finished with a lime greenreflective type color to facilitate ready identification under fireconditions as seen in FIG. 6B.

Once again it is noted that other cover colors and methods of applyingthe color and finishes to the cover are within the scope of theembodiment, but a green color is preferred because it is readilyvisible. This metal cover will contain a keyway 537 and two indentedslots 536D approximately 2 inches apart on its top surface as seen inFIG. 6B. Permanently affixed to cover 536C is a brazed, hex shaped, ⅜inch attachment rod 536F, which will extend completely through theapproximate center of the threaded stem pipe extension 540 as well asthe center orifice of metal stream director 541. The opposite end ofattachment rod 536F will be screwed into a threaded, female coupling536G that is brazed to the interior side of outer metal cover 543 justpast the leading edge of the threaded pipe extension 540 or optionalstream director 541. The outer metal cover 543 will be secure, watertight, decorative in appearance and flush with the interior wall surfaceor ceiling of the space being protected.

A brief description of the operation of this fifth embodiment will nowbe provided. In use, the firefighter will simply insert a 1620 key(typically carried by firefighters) into a keyway 537, turn it counterclockwise ¼ turn and unlock the cover. Once the cover is unlocked thefirefighter will then insert the fork end of a Halligan tool (alsotypically carried) or similar tool into indented slots 536D on thesurface of the lime green cover 536C and turn counter clockwise andremove cover 536C. Upon turning the lime green cover 536C counterclockwise with the fork end of the Halligan tool attachment rod 536Fwill back out of female coupling 536G that is brazed to the interiorside of outer metal cover 543, thus permitting outer metal cover 543 todetach and fall to the floor. At the same time attachment rod 536F andlime green cover 536C will be removed from the opening in the wall orfloor as a single unit. Next, the main stream tip 513 is inserted intoopening in the wall or floor against pivoting ball joint nozzle stop504. It should be noted that this will result in a ½ inch forwardmovement of the main stream tip 513. At the same time, the main streamtip collar 513A will pass locking pins, locking balls or locking rings507 and lock the nozzle in place. Once the decision to start water ismade, the control handle 113D on the controlling nozzle 113C will beopened and the back pressure from the operation of the hose stream willcause the movable connection body nozzle guide/stop 510 and attachedhigh heat resistant rubber seal 510C to be physically forced backwardoff the outer surface of inward socket guide/stop 514 permitting theforward nozzle stop bevel 504A to rest unimpeded on the inwardly roundedor slightly tapered edge of the inward socket guide/stop 514 allowingthe connection to operate similar to that of a conventional ball andsocket as seen in FIG. 1C. The spring release mechanism 508 with knurledlocking collar is visible around the perimeter of the cylindrical metalhousing 536. As in the previous two embodiments, stem pipe 540 isfixedly attached to securing bracket 524 and covers the water exposingend of the quick connect device. However, it should be noted that sincethe nozzle is moveable in this embodiment to 12 degrees above and belowthe horizontal in all directions the direction of this solid waterstream within the larger attached stem pipe 540 will have a notableadvantage, which will permit this solid stream to be more accuratelydirected toward the angular holes in the stream director 541 and thusafford greater reach and control of the stream direction being sought.Upon retraction of the nozzle the stem pipe opening with or withoutoptional attached metal stream director 541 will be sufficient tomaintain a fresh air supply, air quality assessment, camera insertionand also permit limited ventilation of the involved area.

Once a decision is made to remove the main stream tip 513 from thecylindrical metal housing in the wall or floor the water supply is shutdown. The firefighter will depress the spring release mechanism 508 withknurled locking collar located on both sides of the main stream tip 513with the thumb and index finger of one hand and push the locking collar508 forward. This will permit the release of the locking pins, lockingballs or locking rings 507 from the main stream tip collar 513A and theretraction of the main stream tip 513 from the cylindrical metal housingwith the other hand.

Figures 6C generally shows a configuration for a wall or floor of a roomor vessel according to the fifth embodiment with a variation inconstruction. In this instance comprising a high heat resistant rubberguide/stop 510B is used instead of locking pins, locking balls orlocking rings are used. The installation of this variation of the fifthembodiment will be briefly described. A 6 inch hole is drilled in thewall or floor for the purpose of installation. Cylindrical metal housing536 measuring 6 inches in diameter with an attached 2 inch flangeconstructed of a fire resistant metal alloy and all attached componentstherein, which include items 502, 510A, 5106, 524, 535, 536, 536A, 537and 540 as shown in FIG. 6C. This cylindrical metal housing 536 isinserted into the wall or floor until the flange 536A is seated firmlyon the wall or floor surface. Securing bracket 524 is an integral partof the cylindrical metal housing 536. The lower portion of the securingbracket 524 contains an inside pipe thread 535 measuring approximately 2inches in diameter that accepts a threaded stem pipe extension 540 ofvariable lengths (e.g. depending on the thickness of the wall or floorof the room or space to be protected). The lower portion of stem pipeextension 540 will contain an inside thread that will accept a compact,optional, metal stream director 541, which will contain a male thread atits end that permits it to be screwed directly into the lower portion ofstem pipe extension 540. Stream director 541 will contain nine orifices.The center orifice of the stream director will be in line with stem pipeextension 540 while the additional orifices will permit streamdisbursement at an approximate 360 degree angle respectively.

The installation of the variation of this fifth embodiment also includesdrilling ¼ inch by 2¼ inch deep holes into the wall or floor from theexterior side at the predrilled holes 536B located around the perimeterof the flange 536A using the flange as a template. The entirecylindrical metal housing with attached flange is then removed and leadconcrete shields or anchors are inserted into the previously drilledholes. It is noted that other types of wall anchors can be used toattach the flange to the wall, but shields or anchors are preferred.Next, the cylindrical metal housing is reinstalled lining up thepredrilled holes in the flange with the lead concrete shields and then ¼inch by 2¼ inch one way screws with rubber retaining washers attachedare inserted through predrilled holes 536B in flange 536A and the screwstightened until the flange is seated properly on the wall or floorsurface. Finally, a lime green cover 536C having threads on its outerperimeter is screwed into flange 536A having corresponding matingthreads on its inner surface along with attached high heat resistantO-ring 536E which is placed into the flange 536A. This cover will beflush with the flange and finished with a lime green reflective typecolor to facilitate ready identification under fire conditions.

Once again it is noted that other cover colors and methods of applyingthe color and finishes to the cover are within the scope of theembodiment, but a green color cover is preferred because it is readilyvisible. This metal cover will contain a keyway 537 and two parallelindented slots 536D approximately 2 inches apart on its top surface.Also, permanently affixed to cover 536C is a brazed, hex shaped, ⅜ inchattachment rod 536F, which will extend completely through theapproximate center of the threaded stem pipe extension 540 as well asthe center orifice of metal stream director 541. The opposite end ofattachment rod 536F will be screwed into a threaded, female coupling536G that is brazed to the interior side of outer metal cover 543 justpast the leading edge of the threaded pipe extension 540 or optionalstream director 541. The outer metal cover 543 will be secure, watertight, decorative in appearance and flush with the interior wall surfaceor ceiling of the space being protected. A brief description of theoperation of this fifth embodiment will now be provided.

In use, the firefighter will simply insert a 1620 key (typically carriedby firefighters) into a keyway 537, turn it counter clockwise ¼ turn andunlock the cover. Once this cover is unlocked the firefighter will theninsert the fork end of a Halligan tool (also typically carried byfirefighters) or similar tool into indented slots 536D on the surface ofthe lime green cover 536C and turn counter clockwise and remove thecover. Upon turning the lime green cover 536C counter clockwise with thefork end of the Halligan tool attachment rod 536F will back out offemale coupling 536G that is brazed to the interior side of outer metalcover 543, thus permitting outer metal cover 543 to detach and fall tothe floor. At the same time attachment rod 536F and lime green cover536C will be removed from the opening in the wall or floor as a singleunit. Next, the main stream tip 513 is inserted into the opening incylindrical metal housing 536 and then passed through the center openingof high heat resistant rubber nozzle guide/stop 510B. This high heatresistant rubber nozzle guide/stop is compressed within internal housingassembly 536 and located around the interior circumference of thisopening. The nozzle will rest on the high heat resistant rubberguide/stop 510B and be in contact with it around its entirecircumference permitting directional support, but in no way impede orhinder the quick removal of the nozzle. Once a decision is made toremove the nozzle, the water supply is shut down. The firefighter willsimply retract the nozzle by pulling it backward through the high heatresistant rubber guide/stop 510B. As in the previous embodiments, stempipe 540 is fixedly attached to securing bracket 524. However, it shouldbe noted that since the nozzle is moveable in this embodiment in alldirections the direction of this solid water stream within the largerattached stem pipe 540 will have a notable advantage, which will permitthis solid stream to be more accurately directed toward the angularholes in the stream director 541 and thus afford greater reach andcontrol of the stream direction being sought.

Upon retraction of the nozzle the stem pipe opening with or withoutoptional attached metal stream director 541 will be sufficient tomaintain a fresh air supply, air quality assessment, camera insertionand also permit ventilation of the involved area.
